The lack of ballista coverage in CI came up again with @gaojun2048 @liukun4515 and @mingmwang
on apache/datafusion#2070 (comment)

I can take this task in the Q2

Thank you @liukun4515 ! In case you missed it, the setup I had in apache/datafusion#688 already works and was only paused pending optimizations to reduce cache size. I imagine you might be able to reuse some of the setup there when you start working on this this task.

Should we consider running the integration tests in CI without creating docker images? Just run the native binaries for scheduler and executor?
